PTL 1: Japanese Patent No. 4290941
SUMMARY
Technical Problem
We are witnessing increased use of an aerosol container which is
configured by a single container containing two types of contents
separately and by a mounting cup including two stems. However, when
the dispenser described in Patent Literature 1 is applied to such a
container, the aforementioned tab portion interferes with the
mounting cup of the aerosol container. Although the tab portion may
be positioned above the mounting cup in an attempt to avoid the
interference, this attempt leads to an increased size of the
dispenser. Besides, since the tab portion described in Patent
Literature 1 is positioned inside the cover body, the coupling
member cannot be removed without having to insert a finger into the
cover and hold the tab portion. Accordingly, there is still room
for improvement in terms of ease of the removal.
The present disclosure is to solve the above problem, and the
present disclosure is to propose a novel dispenser for an aerosol
container that is configured to be fitted to an aerosol container
including two stems and that facilitates the removal of the
coupling member from the cover.
Solution to Problem
One of aspects of the present disclosure resides in a dispenser for
an aerosol container. The dispenser includes: a fixed platen
configured to be fitted to a mounting cup of an aerosol container
including two stems; a coupling member provided with two coupling
holes through which contents dispensed from the two stems pass
separately; a cover that includes an inner tubular portion
configured to surround the two coupling holes and define passages
for the contents and that also includes an outer tubular portion
configured to cover the mounting cup; and an application member
including a dispensing port through which the contents are
dispensed from the inner tubular portion to outside. The cover
includes at least one cut-out portion formed by cutting part of the
outer tubular portion, and the coupling member includes at least
one first tab portion configured to be accommodated in the at least
one cut-out portion.
In a preferred embodiment, the at least one cut-out portion
comprises a pair of cut-out portions disposed to sandwich the
mounting cup, and the at least one first tab portion comprises a
pair of first tab portions disposed in correspondence with the pair
of cut-out portions.
In another preferred embodiment, the fixed platen includes an outer
circumferential wall configured to surround the at least one
cut-out portion and the at least one first tab portion.
In yet another preferred embodiment, the coupling member includes:
a lower member including two connecting tubes configured to be
coupled to the two stems; an upper member including a rod-like
portion and the two coupling holes; a hinge connecting the lower
member and the upper member in an openable and closable manner,
wherein the lower member includes the at least one first tab
portion, and the upper member includes at least one second tab
portion.
Advantageous Effects
In the present disclosure, the cover includes the outer tubular
portion that is configured to cover the mounting cup and that
includes the at least one cut-out portion. Furthermore, the
coupling member includes the at least one first tab portion
configured to be accommodated in the at least one cut-out portion.
The above configurations prevent the interference to the mounting
cup and do not lead to the increased size of the dispenser.
Moreover, the fact that the at least one first tab portion is
configured to be accommodated in the at least one cut-out portion
provided in the outer tubular portion omits the need for inserting
a finger into the cover during the removal of the coupling member
from the cover. This facilitates the removal of the coupling
member.
When the at least one cut-out portion comprises the pair of cut-out
portions disposed to sandwich the mounting cup, and the at least
one first tab portion comprises the pair of first tab portions
disposed in correspondence with the pair of cut-out portions, the
following advantageous effect is provided. That is to say, the
coupling member may be held by pinching these cut-out portions by,
for example, the thumb and the index finger, and accordingly, the
removal of the coupling member from the cover is further
facilitated.
When the fixed platen includes the outer circumferential wall
configured to surround the at least one cut-out portion and the at
least one first tab portion, the cut-out portion and the first tab
portion are covered by the outer circumferential wall. This
improves appearance and moreover, prevents unwanted contact with
the first tab portion.
When the coupling member includes: the lower member including the
two connecting tubes configured to be coupled to the two stems; the
upper member including the rod-like portion and the two coupling
holes; the hinge connecting the lower member and the upper member
in an openable and closable manner, wherein the lower member
includes the at least one first tab portion, and the upper member
includes the at least one second tab portion, the following
advantageous effect is provided. That is to say, the at least one
first tab portion may be grasped by fingers of one hand, and the at
least one second tab portion may be grasped by fingers of the other
hand, for cleaning the inside of the coupling member. Thus, the
coupling member becomes easier to open.

DETAILED DESCRIPTION
A dispenser for an aerosol container according to the present
disclosure will be described more concretely with respect to the
drawings. Note that in the specification, the claims, and the
abstract herein, the side on which a dispenser for an aerosol
container is positioned with respect to an aerosol container is
defined as upper direction, and the opposite side is defined as
lower direction.
In FIGS. 1 to 3, reference numeral 1 denotes a dispenser for an
aerosol container (that is hereinafter called "dispenser")
according to one of embodiments of the present disclosure. The
dispenser 1 includes a fixed platen 2, a coupling member 3, a cover
4, and an application member 5. Reference numeral 6 denotes an
aerosol container to which the dispenser 1 is fitted.
The aerosol container 6 is configured by a bottomed tubular
container main body 10, which may be made of synthetic resin, and a
mounting cup 11, which may be made of metal. The mounting cup 11
has an outer edge fixed to the container main body 10 by seaming.
The mounting cup 11 of the present embodiment includes an annular
portion 12, which is seamed to the container main body 10, and a
mounting cup's main body portion 13, which is positioned above the
annular portion 12 and which has a partially flat circumferential
side surface. The aerosol container 6 includes a total of two stems
14, which communicate with container space for the contents. The
two stems 14 protrude upward from the mounting cup's main body
portion 13.
The fixed platen 2 includes an upper wall 21, which is provided in
a middle portion thereof with an opening 20. The two stems 14 are
exposed through the opening 20. The fixed platen 2 also includes a
cylindrical side wall 22, which surrounds the side surface of the
mounting cup's main body portion 13. The side wall 22 of the
present embodiment includes a rib 23 in a position corresponding to
the flat part of the side surface of the mounting cup's main body
portion 13 (refer to FIG. 2). The rib 23 prevents rotation with
respect to the mounting cup's main body portion 13. The side wall
22 is provided, in a lower end thereof, with a flange 24, which
extends to the outer side in the radial direction. The flange 24 is
provided, in a lower portion thereof, with a fitting wall 25, which
surrounds the annular portion 12 and which is held to the annular
portion 12 so as not to slip out. The side wall 22 also includes,
in an outer end of the flange 24, an circumferential outer
circumferential wall 26, which extends vertically with respect to
the flange 24.
As illustrated in FIGS. 4A and 4B (which illustrate an opened state
of the coupling member 3), the coupling member 3 is configured by a
lower member 30 and an upper member 31, which are integrally
coupled via a thin hinge 32. The coupling member 3 may be folded
via the hinge 32 into a closed state illustrated in FIGS. 1 and
2.
The lower member 30 includes a lower member's main body 33, which
has a flat plate shape. The lower member's main body 33 is
provided, on the lower side thereof, with two connecting tubes 34,
which are coupled to the two stems 14. On the inner side of each
connecting tube 34, there is provided a through hole 35, which
passes through the lower member's main body 33. The contents
dispensed from the stems 14 pass through the through holes 35. The
lower member's main body 33 is also provided, on the upper side
thereof, with a lower annular wall 36, which surrounds the two
though holes 35, and a pair of lower partition walls 37, which is
positioned between the two through holes 35. Furthermore, as
illustrated in FIG. 1, the lower member's main body 33 is provided,
on both outer ends on both sides thereof, with lower tab portions
(first tab portions) 38, which extend downward. Each lower tab
portion 38 has an outer surface provided with projections 38a,
against which fingers may be placed.
The upper member 31 includes an upper annular wall 39, which abuts
against the lower annular wall 36 in a liquid-tight manner. The
upper annular wall 39 has an outer circumferential surface, which
is provided with a pair of support walls 40, which extend to the
outer side (refer to FIGS. 2 and 5). On outer ends of the support
walls 40, there are also provided upper tab portions (second tab
portions) 41, which extend vertically with respect to the support
walls 40. Herein, one of the upper tab portions 41 has a lower end,
in which the aforementioned hinge 32 is provided. The other one of
the upper tab portions 41 has a lower end, in which a claw portion
42 is provided. The claw portion 42 is configured to engage with
the lower member's main body 33 when the coupling member 3 is in
the closed state. The other one of the upper tab portions 41 is
also provided, on the upper side thereof, with projections 41a,
against which fingers may be placed.
The upper annular wall 39 is also provided, in an upper end
thereof, with a ceiling wall 43, which has a middle portion
protruding upward in the shape of a cylinder. As illustrated in
FIG. 1, on the inner side of the ceiling wall 43, an upper
partition wall 44 is provided. The upper partition wall 44 is
configured to fit in between the pair of lower partition walls 37.
On the upper side of the ceiling wall 43, a total of two holes
(coupling holes) 45 are provided. The coupling holes 45 are
disposed on both sides of the upper partition wall 44 and extend
through the ceiling wall 43 (refer to FIGS. 1 and 5). When the
coupling member 3 is in the closed state, passages for the contents
are defined between the lower member 30 and the upper member 31.
The contents from the two stems 14 flow from the through holes 35
to the coupling holes 45 separately along the passages.
The ceiling wall 43 is also provided with a rod-like portion 46,
which extends upward from between the coupling holes 45. The
rod-like portion 46 has an outer circumferential surface provided
with a flange portion 48, which is configured by a plurality of
semi-circular pieces 47.
As illustrated in FIG. 1, the cover 4 includes a cylindrical inner
tubular portion 50, which is configured to surround the rod-like
portion 46, the flange portion 48, and the two coupling holes 45
and to abut against the ceiling wall 43 in a liquid-tight manner.
That is to say, after passing through the two coupling holes 45
separately, the two types of contents flow through the inner
tubular portion 50 while being swirled by the flange portion 48.
This promotes mixture of the contents.
The inner tubular portion 50 is provided, in an upper end thereof,
with a top wall 51, which extends to the outer side. The top wall
51 is provided with a cover's annular wall 52, which extends
upward. The top wall 51 is also provided, in a middle portion
thereof, with a cover's through hole 53, which communicates with
the inside of the inner tubular portion 50. On an outer end of the
top wall 51, the cover 4 also includes an outer tubular portion 54.
The outer tubular portion 54 extends downward to surround the inner
tubular portion 50 and to cover the mounting cup 11. The outer
tubular portion 54 is also configured to fit in between the side
wall 22 and the outer circumferential wall 26, which are included
in the fixed platen 2 (refer to FIG. 1). The outer tubular portion
54 is provided with at least one cut-out portion 55, which is
formed by cutting part of the outer tubular portion 54 upward from
the lower side thereof. The at least one cut-out portion 55 is
configured to receive the lower tab portions 38. In the present
embodiment, the pair of cut-out portions 55 is disposed to sandwich
the mounting cup 11. The lower tab portions 38 and the cut-out
portions 55 in the present embodiment are covered by the outer
circumferential wall 26, and this contributes to better
appearance.
As illustrated in FIG. 2, the outer tubular portion 54 includes a
pair of operation pieces 56, which expand to the outer side in the
radial direction and then extend downward. Each operation piece 56
has an inner surface provided with an inclined portion 57. The
operation piece 56 herein is configured so that the inclined
portion 57 abuts against a lower end of the outer circumferential
wall 26 when the operation piece 56 is pressed from the outside.
When the operation pieces 56 are pressed from the outside, the
cover 4 is displaced downward along the inclined portions 57.
Accordingly, the coupling member 3 and the two stems 14 are
displaced downward.
The application member 5 includes a dome-like wall 60, which is
configured to be disposed above the top wall 51 and to be fitted to
and held by the application member 5. The dome-like wall 60 is
provided, on a lower surface thereof, with an application member's
annular wall 61, which is configured to abut against the cover's
annular wall 52 in a liquid tight manner. The dome-like wall 60 is
provided, in a middle portion thereof, with a dispensing port 62,
through which the contents, after passing through the cover's
through hole 53, are dispensed to the outside. The dispensing port
62 in the present embodiment is formed in the shape of a slit. The
dome-like wall 60 is also provided with a comb portion 63, which is
used to apply the contents dispensed from the dispensing port 62 to
a subject, such as hair, while combing the subject.
To dispense the contents from the aerosol container 6 by using the
dispenser 1 configured as above, the operation pieces 56
illustrated in FIG. 2 need to be pressed from the outside.
Consequently, the cover 4, together with the coupling member 3 and
the two stems 14, is displaced downward. As illustrated in FIG. 1,
in the present embodiment, the outer tubular portion 54 of the
cover 4 is configured to fit in between the side wall 22 and the
outer circumferential wall 26, which are included in the fixed
platen 2. The outer tubular portion 54 therefore serves to guide
the cover 4 to be displaced straight downward during the downward
displacement of the cover 4. Then, the two types of contents, which
are dispensed from the downwardly displaced stems 14, pass through
the through holes 35 and the coupling holes 45, flow through the
inner tubular portion 50 while being swirled by the flange portion
48, and are dispensed from the dispensing port 62 via the cover's
through hole 53. Subsequently, by moving the aerosol container 6
with the comb portion 63 being pressed against hair or the like,
the contents may be applied while hair or the like is combed.
To clean the coupling member 3, the cover 4 needs to be pulled
upward with respect to the aerosol container 6 as illustrated in
FIG. 6. Consequently, the cover 4 may be removed while the fixed
platen 2 remains on the aerosol container 6.
Since the pair of cut-out portions 55, which is provided in the
outer tubular portion 54, receives the lower tab portions 38 of the
coupling member 3, the cover 4 may be grasped by fingers of one
hand, and the coupling member 3 may be grasped by pinching the
lower tab portions 38 with fingers of the other hand. Then, by
bringing both the hands away from each other, the coupling member 3
may be removed from the cover 4 as illustrated in FIG. 7. At this
time, the contents pooled in the inner tubular portion 50 of the
cover 4 are scraped by the flange portion 48 of the coupling member
3. This makes it easier to clean the inner tubular portion 50.
After the removal, by grasping the pair of lower tab portions 38,
which is provided in the lower member 30, by pinching them with
fingers of one hand and by grasping the pair of upper tab portions
41, which is provided in the upper member 31, by pinching the upper
sides thereof, the claw portion 42 is disengaged from the lower
member's main body 33. In this way, the coupling member 3 may be
brought into the opened state as illustrated in FIG. 4.
Consequently, the inside of the coupling member 3 is ready for the
cleaning. Additionally, the projections 38a, which are provided in
the lower tab portions 38, and the projections 41a, which are
provided in the upper tab portions 41, serve as projections against
which fingers may be placed. These projections prevent slippage
when the coupling member 3 is removed from the cover 4 or when the
coupling member 3 is opened.
Although the configuration and advantageous effects of the present
disclosure have been described above, the dispenser for an aerosol
container according to the present disclosure is not limited to the
above embodiment, and various changes may be made within the scope
of the claims. For example, although in the above embodiment the
comb portion 63 extends upward, the comb portion 63 may extend
obliquely with respect to the aerosol container 6 by attaching the
application member 5 obliquely with respect to the cover 4.
Furthermore, although in the above embodiment the cover 4 and the
application member 5 are configured as separate members, they may
be coupled integrally. Moreover, although in the above embodiment
the cover 4 is displaced downward via the operation pieces 56, the
operation pieces 56 may be omitted. In this case, the cover 4 may
be displaced downward directly. Moreover, the rod-like portion 46
and the flange portion 48 do not necessarily need to be provided in
the coupling member 3.
